DOOR-HANGER.

which the following'isa full, clear, concise,.

and exact description, reference being had to the accompanying drawings, forming a part'of this specification. The present invention relates to door hangers.

Sliding or rolling doors. present many advantages in building construction an the like, but proper installation of the same has been secured only where great care and accurate workmanship have been exercised.

It is an object of the present invention to provide an improved hanger for doors which will secure to a'maximum de ree the advantages of a sliding or rolling oor and which will allow of accurate, quick and convenient installation with'a minimum'of difficulty. The invention also provides means for securing continuously successful and satisfactory operation after the door is installed.

It is a further object to provide means for adjusting the height of the door to facilitate alinement of the door with the opening.

In Figure 1 I have shown an elevational View with parts broken away to show the location of the hangers on the top of the door and with'their rollers resting in the track provided over the door.

I provide a base or br fret which at its lower end is provided with countersunk holes for the reception of the holding screws 2and 3, which fasten the hanger to the doorframe 4. At its upper end the bracket 1 is provided with a cylindrical lug ornroiec- Specification of Letters Patent.

tion 5, which is provided with corrugations 6 adapted to fit into similar corrugations on the arm 8 of the roller-supporting portion of the hanger. A screw 9 binds the elements 5 and 8 together, and a set-screw 10 is adapted to bear upon the screw 9 and hold it in positionso'that when a certain position of the door is decided upon that-adjustment may be secured, the double-screw holding means insuring a permanence of adjustment; The corrugations 6 and 7 prevent slipping and aid in the proper adjustment of the door, as will be. described later.

The arm 8 is fashioned into a hollow ring 11 at one end. The outer periphery of this 'ring, 12, is cylindrical, but the inner periphery, 13, is grooved to provide a race for the ball bearings 11., The roller is composed of two halves 15 and 16 (best shown in Fig. 2), which are placed upon opposite sides of the ring 11 and are secured together by means of the screw 17. A screw 18 is provided to prevent relative angular displacement of the two elements 15 and 16. The adjoining surfaces of the two elements are angularly recessed adjacent their peripheries as indicated at 19 and 20 to provide a channel bearing surface for the ball bearings 14.

- The peripheries of the sections 15 and 16 of the roller are beveled as at 21 and 22 to readily engage the grooved trackway 25, the latter being mounted over the door by an angle iron 25 which is in turn retained in supporting position by means of a rivet 28.

The outer edge of the roller is rounded or beveled as hereinbefore described; that to say, the outer surface of the roller approximates the surfacepfa sphere or of an oblate spheroid of approximately the same curvature as that of the groove or channel in the track. 25., 'From this it will be apparent that even if the plane of the roller and the planeof the track do not coincide, such skewing of the roller will have a minimum detrimental eflect and will not cause a grinding noise, as is common in .fianged rollers, nor will there be the same tendency to jump the track. It will be seen that in the construction of Figs. 1, 2 and 3 .;tl1e same bracket and roller serve for botheiidsydf the door. By means of the elbow construction it is possible to have the rollers at or even beyond the extreme edges of the door. This gives an elongated base of support, reducing the tendency of the door to tilt or skew.

The adjusting and fastening screws are all arranged on the bracket side so that they will occupy a minimum thickness and will at the same time be accessible.

It will be evident that when the bracket 1 is secured to the door-frame the roller-bearing arm 8 will be movable about the pivot 9 until the latter is tightened. Often after a door is hung it is found that it is not hanging straight, one of the door ends being higher or lower than the other end. My invention provides a means for securing the proper adjustment of the door without having to take the door down. For such adjustments the corrugations 6 and 7 are provided, so that when the screws 9 and 10 are loosened, a slig't rotation for one or two notches will result in the raising or lowering of the door. When the door has been raised or lowered the desired extent the screws 9 and 10 are once more tightened and a lasting adjustment is secured.

In Figs. 4 and 5 I have shown a modification of the adjusting means. Here the rear end of the arm 8 is provided with a projection 30. The bracket 1 is also provided with a projection or ear 31, through which a bolt 32 passes and engages with the lug 30. A nut 33 is placed upon the screwbolt for the purpose of locking the bolt 32. It will be evident that this modification provides means for obtaining a finer ad ustment of the height of the door than that shown in Figs. 1, 2 and 3. If the hanging of the door is found to be faulty, as having one end higher or lower than the other, or it is desired to have the entire door raised or lowered, it is'only necessary to mani ulate the bolt 32 properly in order to e ect the desired result. -r.

In Figs. 6, 7 and 8 I.have shown another modification of the hanger. Here the connection between the base element 1 and the roller-bearing arm 8 is a rigid one and not pivoted, as above described. I have here shown the lug 5 of the bracket 1 as rectangular in shape and provided with corrugations 6 which are horizontal and parallel. The arm 8 of the roller'supporting portion of the hanger is providedwith corrugations 1' adapted to fit into the corrugations 6 of the bracket. The arm 8 is provided with a flan e 35 which bears against the edge of the lug 5 and tends to hold the elements 5 and 8 in alinement. Screws 9 and 10, similar to those before described, are provided to secure together the elements 5 and 8.

The roller shown in Fig. 8 is of somewhat more unitary and economical construction than that before described. It is composed of the two halves 15 and 16 which halves are of such construction that they may be stamped or pressed out of sheet metal. The inner periphery of the hollow ring 11 provides a race for the ball bearings 14, as before described.

This construction of the roller providesprovided by the radial corrugations. Here for each difference in elevation of the corrugations themselves the roller will be raised or lowered the same amount so that the door is raised and lowered a distance exactly equal to that made at the corrugations themselves. In the case of the radial corrugations, for a rotation of one corrugation, the center of the roller portion will move on the arc of a circle whose center is at the center of the radial corrugations and the door will be raised or lowered a correspondingly larger amount, due to this arrangement, than for a variation of one corrugation where the same are horizontal and parallel, and therefore a nicer adjustment of the door is obtained by means of the latter.

It is to be noted that instead of ball bearings, roller bearings or a plain cylindrical or any other bearings may be provided.

It will be noted that the ring 12 rides above the surface of the groove in the track 25. This allows a space for the dust to accumulate without coming under the surface of the roller. Periodical brushing of the track will thus keep the track and rollers constantly clean.

The above described embodiment illus-.

trates only typical forms in which my in vention may appear. I do not intend to be limited to these specific forms and numerous modifications will at once he suggested to those skilled in the art. I desire that my invention be construed as broadly as is con sistent with the spirit and scope of the appended claim.

What I claim is:

In combination, a trackway comprising a solid bar with a semi-circular groove in its upper face, an object carrying arm provided with a bearing located centrally over said groove, a roller having a double running surface, one tread thereof engaging one side of said groove and the other tread engaging ing, of greater diameter than the bearing space at the deepest point of the trackway which is not in Contact with the roller, to receive dust, dirt, and the like.

In witness whereof, I hereunto subscribe my name this 21st day of January A. D. 1915.
